Conditions We Treat

Acid Reflux (GERD)

Heartburn or acid reflux (GERD) can cause a lot of discomfort but can also be damaging to the esophagus (esophagitis).   After a long time, acid damage can lead to Barrett’s esophagus or cancer of the esophagus.

Bloating, gas, abdominal distension

These can be signs of small intestinal bacterial overgrowth (SIBO) a type of irritable bowel syndrome (IBS).  A variety of other causes can be responsible as well.   We can test, diagnose and treat abdominal bloating.

Irritable Bowel Syndrome (IBS)

IBS is a name used for several different bowel problems.  It can be gas and bloating or abdominal cramping pain.  It may include diarrhea, constipation or both.  We want to exclude a more serious problem.   We use medical therapy as well diet and life style changes in treatment of IBS.

Pylori Infection

Pylori is a bacteria that can infect and live in the stomach for many years. H. pylori can cause indigestion, gastritis, stomach ulcers or even stomach cancer. We have state of the art breath testing conveniently in the office and routinely treat H. pylori infection.

Hiatal Hernia

Hiatal hernias area very common and can lead to acid reflux disease or heart burn.  A treatment plan with diet changes and possibly medications can help alleviate symptoms.  Sometimes a hiatal hernia is very large and may need surgical correction.

Stomach Ulcers

Ulcers can cause abdominal pain or bleeding.  They can be caused by H. pylori or certain medications.  We can test for ulcers and treat them.   We also treat H. pylori infection to prevent ulcers from returning.

Swallowing Difficulties

Swallowing problems or Dysphagia can have many sources and should be taken seriously.  It may be a difficulty with starting the swallow process or food can get stuck in chest after swallow. An x-ray study or an upper endoscopy can diagnose and allow correct treatment.

Esophagus Cancer

Esophagus cancer is diagnosed by an upper endoscopy.  We also recognize and treat conditions that increase the risk for esophagus cancer such as acid reflux or Barrett’s esophagus.

Barrett’s Esophagus

Barrett’s esophagus is a condition that increases the risk of esophagus cancer and can be caused by chronic acid reflux.   We are able to screen for Barrett’s esophagus and provide a treatment plan that would include medication, life style changes and screening.

Colon polyp & Colon cancer;  Rectal polyp & Rectal Cancer

Colorectal polyps can lead to colon cancer or rectal cancer.  We can detect and remove polyps during a colonoscopy procedure.

Rectal Bleed

Rectal bleed or blood in stools should not be ignored. It could be caused by hemorrhoids or an anal fissure. It could also be a sign of rectal cancer or colon cancer.

Anal Cancer

Anal cancer can come about from a virus, specifically HPV (Human Papilloma virus). We offer and encourage screening for anal HPV and anal cancer for those that are at a higher risk for anal cancer. We offer anoscopy, a quick office procedure, that can detect many anal problems.

Anal Fissure

Fissures are small cuts in the anal area that are very painful. We can diagnose and treat anal fissures at our office.

Fatty liver

We offer a well-rounded approach to treatment of fatty liver which can be part of metabolic syndrome. Therefore, we consider obesity, high cholesterol, high blood pressure, diet, exercise and lifestyle in patients with fatty liver. We also offer fibrospect and fibroscan testing to check for fibrosis (scarring of the liver).

Diarrhea

Diarrhea may have many causes. We are able to do a complete evaluation for the many causes of diarrhea.

Anemia and Iron Deficiency

Anemia or iron deficiency can be a sign of blood loss through the gastrointestinal tract.  Anemia can be a serious condition and needs further evaluation.

Hemorrhoids

Hemorrhoids can cause significant pain or rectal bleeding. Hemorrhoids can be treated at times with medications or a minimally invasive office procedure.

 

Celiac Disease

Celiac disease is a type of gluten sensitivity. It can cause anemia, iron deficiency, diarrhea, abdominal pain or certain cancers. We diagnose and formulate a comprehensive plan of treatment for those with Celiac disease.

Diverticulitis

Diverticulitis is a condition where small pockets within the colon become inflamed and infected. These small pockets form as we age. Diverticulitis usually causes significant abdominal pain and may require prompt treatment antibiotics.

Constipation

Having difficulty with bowel movements, infrequent or hard stools or sensation of incomplete emptying are common complaints. We can test for causes of constipation and treat conditions that lead to constipation.

Inflammatory Bowel disease (IBD):  Ulcerative Colitis, Crohn’s disease

Inflammatory bowel disease includes Ulcerative colitis and Crohn’s disease. Dr. Mehdizadeh is an expert in diagnoses and treatment of Inflammatory bowel disease.

Cancer Prevention

Prevention is the best way to promote health. Early detection saves lives. Many disorders of the digestive tract such as cancers of the colon, rectum and esophagus are easily preventable and may be curable if diagnosed early. For example, removing colon polyps by colonoscopy reduce the risk of colon cancer. Treatment of acid reflux (GERD) and proper evaluation by an upper endoscopy can decrease the risk of esophageal cancer. Eradicating bacteria called H. pylori can reduce the risk of gastric cancer. As a gastroenterologist, Dr. Mehdizadeh specializes in prevention, diagnosis and treatment of common and rare gastrointestinal cancers.
